MOLD FOR CASTING INGOTS OF ALTERNATE LAYERS OF METAL.

SPECIFICATION forming part of Letters Patent No. 320,560, dated June 23,1885.

" A lication filed Ma -ch17, 18M. (Nomodch) To all whom, it may concern:

Be it known that I, J OHN ILLINGWORTH, a citizen of the United States,residing at New ark, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Molds for CastingIngots of Alternating Layers of Metal; and 1 do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to facilitate the process of producingingots of alternating layers of hard and soft steel or other metals, andto reduce the cost of the same.

It consists in the arrangements and combinations of parts substantiallyas will be hereinafter set forth, and finally be embodied in the clausesof the claim.

Referring to the accompanying drawings, embodied in two sheets, in whichsimilar letters of reference indicate like parts in each of the severalfigures, Figure 1 is a side elevation of the improved device, partiallyin section, to show the interna lconstruction thereof. Fig. 2 is a planof the same, showing the center formed in elevation, the base partly insection, the left mold in elevation with its cover on,

'and the right mold in section with its cover off, and with the metalplates and plate-holders in section. Fig. 3 is avertical section takenthrough line 00, and Fig. 4 is a detail plan of the foundation-piece. V

In carrying out the invention I form the mold of several detachablesections, preferably of cast-iron, of which a is the base, havingtherein grooves or passages 72, leading from a central funnel, c, to oneor more upright ingot-molds or plate-receptacles. Said grooves are linedand covered with suitable fire-bricks, Z) Z), the covering-brick beingremovable.

The ingot-molds or plate-receptacles d are formed of foundation-pieces eand hollow uprights h. The foundation pieces e are provided withinclined inner sides, f, and wedgeshaped projections 9, adapted toseparate the lower extremities of the steel plates h when thelatter aredropped into the said molds,

and to hold them at suitable distances apart and from the side walls ofthe receptacles, as will. be understood upon reference to Fig. 1. Uponthe foundation-pieces c are placed the hollow uprights or molds h, whichapp'roximate the length of the plates h.

In casting the ingots, which areto be of alternating layers of differingmetal, I place the metallic plates or bars h longitudinally in thevertical receptacles, the lower ends being separated in the loweringprocess by the wedgeshaped projections g, and brought to a properdistance from the wall of the receptacle by the inclined side surfaces,Said lower extremitiesrest on suitable ledges or shoulders, j, and arethereby held up into proper relative position in the receptacle to allowthe molten metal coming up through the passages 11 to pass around on allsides of the plate or plates h. plates are correspondingly held apartand from the walls of the receptacle by notched cross-strips l and sidewedges, m, as shown in Fig. 3, or by any other suitable means.

The receptacles are provided with a cover, a, to close the mouththereof. Said covers are supported by the notched strips Z and m, whichhold the covers, and the plates h fit loosely, so as to allow theplate'chambers to be vented.

The funnel 0 may be lined with tubular tile or fire-brick s.

In operation the plates h are heated, so as not to chill the moltenmetal, and placed in position in the receptacle, after which the moltenmetal is poured through the funnel 0 and passes through the passage b,entering the receptacles a, and filling the spaces around and betweenthe plates 72, the plates and cast metal forming, whencool, an ingot ofalternating layers.

I do not wish to be understood as limiting myself to the exactconstruction and arrangement of parts shown, as numerous changes may bemade without departing from the spirit of the invention.

\Vhen the metal is hardened, the portion (1 is drawn off by a suitablecrane or othertackling, handles or means 1) being provided to receivesaid tackling.

The upper extremities of the said substantially as and for the purposesset forth;

The combination of afunnel, one or more ingot-molds, one or more metalplates in each mold, and a passage extending from the funnel to eachmold or plate-receptacle, and to a position under the plate or platestherein, whereby the metal passes beneath and upward] y on both sides ofthe plate or plates, as and for the purposes set forth.

4. In a mold for casting ingots of alternating layers of metal, aplate-receptacle having ledges j, inclines f, and guides g,arranged andoperating substantially as and for the purposes set forth.

5. In combination,the base having passages therein, the funnel, theuprights h, and foundation-pieces 6, provided with wedge-shapedprojections, all said parts being arranged and operating substantiallyas set forth.

In testimony that I claim the foregoing I have hereunto set my hand this12th day of March, 188-1.

JOHN ILLINGWORTH.
